cosmicjazz,
The overriding characteristic of good class D amps is their neutrality, nothing is added or subtracted from the inputted signals. I've heard many class D amps and currently own 2 stereo and a pair of mono amps, they're all neutral to the extreme.
In your case of wanting a warmer sound, the best solution I'm aware of is using a tube preamp that you like the sound of and pairing it with a good class D amp of your choice. The overall sound will be determined by the sound of your tube preamp and source components since the class D amp virtually has no sound of its own.
I used a VTL 2.5L tube preamp with and replaced the standard Russian or Chinese tubes with NOS (new old stock) Mullard tubes for a warmer, more dimensional sound. I paired this with first a Class D Audio SDS-440-CS stereo amp and later an Emerald Physics EP-100.2-SE stereo class D amp and it provided overall the sound of a very good tube amp with very good bass, a rare combination that sounds like something you'd really enjoy.
